animal enrichment
n.— «At one point in the afternoon, an Oakland Zoo employee tossed two boxes covered in camel hair and filled with meat cutlets into the tiger pit, a process called “animal enrichment” that simulates prey. The two tigers, whose names the zoo keeps private to prevent people from taunting them, quickly began tearing the meat from the boxes.» —“S.F. Zoo Tiger Attack” by Carri Sturrock San Francisco Chronicle (California) Dec. 27, 2007. (source: Double-Tongued Dictionary)
